Abstract: PURPOSE:To obtain growth layers having different band gap energies by performing epitaxial growth once, by forming an epitaxial layer containing an ultra thin film 500Angstrom  or less thick on a semiconductor substrate having a plurality of regions where mesa-stripes having different widths are formed. CONSTITUTION:The first and second mesa-stripe regions 11 and 11' having different widths are formed on a semiconductor substrate 1. Then, the first and second quantum well layers 15a and 15b which contain an ultra thin film layer (500Angstrom  or less thick) consisting of an epitaxial growth layer and have different band gaps as well are formed on the mesa-stripe regions 11 and 11'. Further, the first and second semiconductor regions 3 and 2 which contain quantum well layers 15a and 15b and are different each other are also formed on the mesa-stripe regions 11 and 11'. Thus, growth layers having different band gap energies may be formed on the same plane at a plurality of regions located on the substrate 1 by performing an epitaxial growth once.

Title: Signal transmission system
Inventor: IWASA KIYOUICHI
IPC: G06F3/00
Filed: 1981-01-20
Abstract: PURPOSE:To realize the transmission of an asynchronous series multiplied signal with  N:1 bus connection, by reducing the waveform distortion noise according to the matching termination of branch lines and at the same time constituting a transmitting circuit so as to release an output during pause of transferring to prevent the disturbance  to the data under the transfering. CONSTITUTION:A branching device is inserted to each branch point of the bus connection to have the matching termination. Thus the waveform distortion noise is reduced  to increase the transfer speed of data. At the same time, each transmitting circuit  which transmits the balanced signal is constituted so as to release the output when the  data is not transferred and when the power supply voltage is applied and cut off. For  instance, the transmitting circuits 1-4 are connected to the branching devices 13-15  via the corresponding AC supply circuits 5-8 and branch transmission lines 9-12; and  at the same time the termination resistances 16-19 are added to the output of the  circuits 1-4. Then the devices 13-15 are connected via a main transmission lines 20- 21, and the other end of the branching device 15 is connected successively to a main  transmission line 22, an AC coupling circuit 23 and a receiving circuit 24 in that order.  At the same time, a termination resistance 25 is added to the input of the circuit 24.

Abstract: PROBLEM TO BE SOLVED: To produce a tin-oxide fiber having a high purity by discharging an alcoholic solution of a halogenated tin compound from a spinning nozzle to form a gel fiber and followed by a heat treatment and a steam treatment. SOLUTION: A spinning solution composed of a highly viscous sol is prepared by dissolving a halogenated tin compound such as stannous chloride or stannous bromide in methanol, etc., to obtain a clear homogeneous solution and then, condensing the obtained solution. A gel fiber is formed by extruding the spinning solution from a spinning nozzle under pressure and continuously winding up on a drum, and subsequently the alcohol and water are removed from the gel fiber. In order to strengthen the fiber skeleton, the fiber is subjected to a heat treatment at 250-1,550 deg.C, preferably 300-1,500 deg.C, and further the fiber is made to contact with steam at >=60 deg.C before, during or after the heat treatment to remove halogen ions in the fiber. Thus, the objective tin-oxide fiber having a high purity is obtained.
